<p class="awabstrak2">The obstacle in planting and developing forage plants is limited land. One solution to anticipate this is to utilize land in plantations by introducing forage shade-tolerant among the main crops. The area of oil palm plantations in Indonesia reaches 14,677,560 ha potentially used in the integration system. This article outlines the superiority of <em>Stenotaphrum secundatum</em> from the selection results so that the reader gets comprehensive information about this grass, both in terms of production, nutritional quality and digestibility. <em>Stenotaphrum secundatum</em> selection’s variety grass is a forage shade tolerant that had derived by positive mass selection method which had had been tried it’s adaptability at two different elevation in North Sumatra. This grass is very suitable to be integrated in plantation land. The average fresh yield of <em>S. secundatum</em> at 55 and 75% shading level reached 2,386 and 2,001 g/m2/harvest, respectively. The digestibility of Steno grass selection’s result on growing Boerka goat shows a fairly good value, which ranges from 60.7% to 72.8%. Palatability of <em>S. secundatum</em> grass in goats is very good with consumption reaching 3.6% of body weight. <em>S. secundatum</em> grass, besides being tolerant of shade, is also resistant to pests, as long as it is maintained with good management. The crossing of polyploid Steno grass with diploid has produced drought tolerant varieties. This grass also has advantages in terms of dry matter production, nutrient content and crude protein production compared to other grass species and can be planted in wider plantation areas with 55-75% shade.</p>

Italian, annual and perennial ryegrasses are the most important grass species cultivated for seed production in the Czech Republic. The straw remaining after seeds threshing can be used as low quality forage, bedding material or as soil amendment. However, there are no comprehensive information concerning grass straw yields and quality in central Europe. The aim of this study was to investigate the Italian (IR) and perennial (PR) ryegrass straw yield and quality. These parameters were measured for two harvest years at two locations. IR did not provide statistically higher straw yield than PR (7.50 and 7.17 t.ha–1 respectively, p = 0.314), but dry matter (DM) content immediatelly after threshing was higher than for PR (0.42 and 0.38 respectively, p = 0.03). IR straw had the same content of ash and hemicellulose (mean 69.8 and 216 g.kg–1 DM, p = 0.22 and 0.57), but less crude protein (64.1 and 81.4 g.kg–1 DM, p = 0.003), more fibre (399 and 382 g.kg–1 DM, p = 0.02), NDF (656 and 629 g.kg–1 DM, p = 0.03) and ADF (442 and 412 g. kg–1 DM, p = 0.000) when compared with PR straw. Most of the parameters were affected by the year (with exception of crude protein) and by location (with exception of yield, DM content, ash and crude protein). There were no differences in mineral nutrient contents between species. The highest values were found in potassium (19.8 g.kg–1 DM) what is comparable with average quality hay. Phosphorus, calcium and magnesium contents (1.42, 2.96 and 1.02 g.kg–1 DM) were substantially lower than in hay. Data concerning ryegrasses straw yield and quality from the USA are comparable with our results and can be used for European conditions.

Cratylia argentea (Desv.) O. Kuntze is a drought-tolerant tropical shrub legume that can help to ensure continuity of forage supply in smallholder systems either through direct grazing or as a cut-and-carry plant for fresh foliage or silage. A collection of 38 accessions was characterized agronomically and nutritionally. High diversity was detected between accessions. Time to flowering ranged from 217–329 days after transplanting seedlings to the field and from 129–202 days after cutting. Flowering is probably induced by reduction of day length. Seed production was high but variable. Dry matter production ranged from 190–382 g/plant in the rainy and from 124–262 g/plant in the dry season, content of in vitro digestible dry matter from 589–690 g/kg, crude protein content from 184–237 g/kg and fibre content from 403–528 g/kg (neutral detergent fibre, NDF), 240–335 g/kg (acid detergent fibre, ADF), and 9–13 g/kg (acid detergent fibre-bound nitrogen, N-ADF). Accessions CIAT 18674 and CIAT 22406 were identified as promising for further study. They were superior to the commercial cultivar in terms of dry matter (DM) production, particularly in the dry season. Further research is required to determine the prevailing reproduction strategy of C. argentea and to quantify outcrossing-rates. Multilocational trials with a selected set of accessions should be conducted under different environmental conditions.

Forage, the main feedstuff for ruminants, includes grasses and legumes, browses, and side products of food crops. However, legumes generally have greater crude protein content relative to other species of forage plants. One of the species of legumes is alfalfa (Medicago sativa), a perennial crop that can grow from the tropics up to sub tropics. In spite of its excellent nutrient content, In Indonesia alfalfa is still not widely explored and used for feedstuff. A study was conducted to explore and evaluate of alfalfa performances in terms of the height, number of tillers, dry matter (DM) and crude protein (CP) productions under the effects of different plant densities and ages of defoliation”. The height of the location of study was 200 m above sea level with an average temperature of 270 C. The results showed that the ranges of the height of alfalfa, the numbers of tillers, DM and CP productions were 33.31-56.32 cm, 36.38-82.36 tillers/bunch, 556.9-1018.9 kg/ha/defoliation, and 149.75 – 291.79 kg/ha/defoliation, respectively. In general, the ages of plant at the time of defoliation and plant distances affected (P<0.05) the variables being studied. The older plants resulted in greater DM and CP yields, and more densely plantation resulted in greater DM and CP yields.Keywords: alfalfa, plant density, defoliation age.

Meadow Bromegrass

Meadow bromegrass (Bromus riparius Rehm.) is a recently introduced pasture grass in western Canada. Its leafy production and rapid regrowth have made it a major grass species for pasturing beef animals in this region. As relatively little breeding work has been done on this species, there is little information on its breeding behaviour. The main objective of this study was to estimate total genetic variability, broad-sense heritability, phenotypic and genetic correlations. Forty-four meadow bromegrass clones were evaluated for agronomic characters. Genetic variation for dry matter yield, seed yield, fertility index, harvest index, plant height, plant spread, crude protein, neutral detergent fiber and acid detergent fiber, was significant. Broad-sense heritability estimates exceeded 50% for all characters. Heritability estimates were at least 3.5 times greater than their standard errors. Phenotypic and genetic correlation between all possible characters were measured. There was general agreement in both sign and magnitude between genetic and phenotypic correlations. Correlations between the different characters demonstrated that it is possible to simultaneously improve seed and forage yield. Based on the results, it appears that the development of higher yielding cultivars with higher crude protein, and lower acid and neutral detergent fibers concentration should be possible.

With the objective of verifying the response of Euterpe oleracea seedlings to seven arbuscular mycorrhizal fungi species, an experimental trial was carried out under greenhouse conditions. Seeds of E. oleracea were sown in carbonized rice husk. Germinating seeds were initially transferred to plastic cups, containing fumigated Reddish Yellow Quartz Sand and inoculated with arbuscular mycorrhizal fungi. Two months later, seedlings were transferred to 2 kg black plastic bags, containing the same soil without fumigation. Plant growth and mineral nutrients were evaluated nine months after mycorrhizal inoculation. Differential effects were observed among the species tested, with Scutellispora gilmorei being the most effective ones in promoting growth and nutrient content of E. oleracea seedlings. The increment resulted from inoculation with S. gilmorei were 92% in total plant height, 116% in stem diameter, 361% in dry matter production, 191% in N, 664% in P, 46% in K, 562% in Ca, 363% in Mg and 350% in Zn contents, comparing to uninoculated controls. Infected root length was positively correlated to nutrient content and plant growth. It was concluded that growth and nutrient uptake of E. oleracea seedlings could be significantly improved by inoculation of effective arbuscular mycorrhizal fungi.

The objective was to evaluate agronomically nine sorghum-sudangrass hybrids (Sorghum bicolor × Sorghum sudanense) and the nutritive value of their respective hays. The experimental design used was randomized blocks in a 3 × 9 factorial scheme, with three replications. Three cuts were made: 42 days after germination, 29 days after regrowth, and 28 days after the second regrowth. All hybrids showed a higher number of plants ha–1 (P < 0.05) in the second cut. For the green matter and dry matter production of the hays, the values ranged from 49.16 to 62.07 t ha–1 and 9.07 to 11.43 t ha–1, respectively. There were no differences (P > 0.05) in dry matter, mineral matter, or ether extract. The hybrids 1013020, BRS 810, 1013016, and 1624F016 showed higher values of crude protein (CP) of 16.49, 16.17, 16.08, and 15.88%, respectively. Differences were observed (P < 0.05) in neutral detergent fiber (NDF) content. The hybrids 1013020, BRS 802, 1013021, 1013016, BRS 810, and 1624F006 presented lower levels of NDF (60.57, 60.74, 62.15, 62.37, 62.58, and 64.70%, respectively). The hybrids BRS 802, 1013016, BRS 810, and 1624F006, stood out above the others, presenting high forage yield and adequate nutritive value (CP content >13% and NDF content <65%).

This study aimed to determine the effect of different processing methods on the proximate composition and anti-nutritional factors of Dolichos lablab beans (Lablab purpureus) of Kenya. The seeds of KAT/DL-2 variety,sourced from Kenya Agricultural Livestock and Research Organisation, Katumani Dryland Research Station were sorted, then subjected to different processing methods (soaking, cooking and germination). The samples were analysed for proximate composition, tannins, phytates and trypsin inhibitory activity. The results showed a significant increase (2.0%) in crude protein content for germinated lablab beans while carbohydrates content was high in cooked samples. The variety KAT/DL-2 had high levels of phytates; 723.6 mg/100g and tannins 330.3mg/100g and trypsin inhibitor activity 1.3mg/100g. Cooking achieved the highest reduction of anti-nutrients with 88% reduction in TIU. The results revealed that the anti-nutrients in lablab beans can be reduced using different methods of processing. However, there is need to investigate the effect of combined methods on the nutrients and anti-nutrients.
